NettetThe IEEE 112 standard is a test procedure that describes motor efficiency testing. The method F is common for very large motors. It also describes most other common poly-phase motor tests. For testing large motors, NEMA MG 1 Sec. 20.16.1 specifically indicates that testing be done per IEEE 112. IEC 60034, with all its parts, is similar to … NettetThe operator sets the voltage of the surge test pulses based on standards and best practices. The test voltage ranges from the peak operating voltage of the motor to …
